SUDUT RELASI KUADRAN IV

270° + dan (360° − ) menghasilkan sudut-sudut di

kuadran IV di dalam trigonometri, relasi sudut-sudut

dinyatakan sebagai berikut.

sin(270° + ) = − cos sin(360° + ) = −sin

cos(270° + ) = sin
cos(360° + ) = cos

tan(270° + ) = −cot
tan(360° + ) = −tan

csc(270° + ) = −sec csc(360° + ) = −csc

sec(270° + ) = csc sec(360° + ) = sec

cot(270° + ) = −tan cot(360° + ) = −cot
